Denmark–Norway (Danish and Norwegian: Danmark–Norge; German: Dänemark–Norwegen) is the historiographical name for a former political entity consisting of the kingdoms of Denmark and Norway, including the originally Norwegian dependencies of Iceland, Greenland and the Faroe Islands. Following the strife surrounding the break-up of its predecessor, the Kalmar Union, the two kingdoms entered into another personal union in 1536 which lasted until 1814. The corresponding adjective and demonym is Dano-Norwegian.

The term Kingdom of Denmark is sometimes used to include both countries in the period 1536–1814, since the political and economic power emanated from Copenhagen, Denmark. The term covers the "royal part" of the Oldenburgs as it was in 1460, excluding the "ducal part" of Schleswig and Holstein. The administration used two official languages, Danish and German, and for several centuries both a Danish and German Chancery existed.

The term Denmark–Norway has didactic merits and reflects the historical and legal roots of that union. It is adopted from the Oldenburg dynasty's official title. The kings always used the style "King of Denmark and Norway, the Wends and the Goths". Denmark and Norway, sometimes referred to as the "twin-realms" of Denmark–Norway, officially had separate legal codes and currencies, as well as mostly separate governing institutions, although following the introduction of absolutism in 1660 the centralisation of government meant a concentration of institutions in Copenhagen. The term Sweden–Finland is sometimes, although with less justification, applied to the contemporary Swedish realm between 1521 and 1809. Finland was never a separate kingdom, and was completely integrated with Sweden, while Denmark was the dominant component in a personal union.

The Kingdom of Denmark (Danish: Kongeriget Danmark, pronounced [ˈkɔŋəʁiːəð ˈdanmɑɡ̊] ( listen)) is a constitutional monarchy and sovereign state consisting the country of Denmark in northern Europe and two autonomous constituent countries, the Faroe Islands in the North Atlantic and Greenland in North America. The kingdom is a unitary state with some power being devolved from Denmark proper to Greenland and the Faroe Islands; this polity is referred to as the Danish Realm. Denmark proper is the hegemonial area, where judicial, executive, and legislative power resides. The Faroe Islands are defined to be a community of people within the kingdom, and the Greenlandic people are defined as a separate people with the right to self-determination.

Denmark is the southernmost of the Nordic countries, located southwest of Sweden and south of Norway, and bordered to the south by Germany. The country consists of a large peninsula, Jutland and many islands, most notably Zealand, Funen, Lolland, Falster and Bornholm, as well as hundreds of minor islands often referred to as the Danish Archipelago.

Norway ⁱ/ˈnɔrweɪ/ (Norwegian:  Norge (Bokmål) or  Noreg (Nynorsk)), officially the Kingdom of Norway, is a Nordic unitary constitutional monarchy whose territory comprises the western portion of the Scandinavian Peninsula, Jan Mayen, the Arctic archipelago of Svalbard and the subantarctic Bouvet Island. Norway has a total area of 385,252 square kilometres (148,747 sq mi) and a population of about 5 million. It is the second least densely populated country in Europe. The majority of the country shares a border to the east with Sweden; its northernmost region is bordered by Finland to the south and Russia to the east; in its south Norway borders the Skagerrak Strait across from Denmark. The capital city of Norway is Oslo. Norway's extensive coastline, facing the North Atlantic Ocean and the Barents Sea, is home to its famous fjords.
